The Doppler Wind Experiment (DWE) uses two ultrastable oscillators (USOs), one on the probe and one on the Cassini orbiter. As the probe drifts due to winds in Titan's atmosphere, a measurable Doppler shift will be induced in the carrier signal. The Doppler signature in the probe radio signal will be extracted on-board the orbiter and merged into the probe data stream recorded on the orbiter's solid-state recorders. It is anticipated that the measurements so obtained will be so sensitive that, by having the probe transmitting antennae offset from the spin axis by just a few centimeters, it will be possible to determine the spin rate and phase of the probe. It may also be that the swinging motion of the probe beneath its parachute and other ... ...Show More
